It so happens I was looking for a way to do multiple autocompletes in a QComboBox.
In other words, I had an editable combo box containing the list:
I wanted the user to be able to type “p” and have it autocomplete to “pie.”
This is no problem. Qt makes this automatic and wonderful, and it is a reason I want to give Qt a hug sometimes.
But then I want the user to keep typing “pie c” and have the combo box autocomplete “pie cupcake.”
This is a bit trickier.
I had seen some code for doing one’s own autocompletion combo box from scratch, and let us just say I did not want to write any.
So I sniffed around and found John Schember’s post about QCompleter and autocompleting multiple entries, and I was saved!
Fortunately, a QComboBox contains a QLineEdit object, so I was able to adapt this code while being very very lazy.
Woot. Thank you, John Schember.
